Weather To Watch

A cold front and slow moving trough is bringing heavy rain, with multiple flood warnings current across the state.

The Bureau of Meteorology says a low pressure system will form to the east of Tasmania Saturday afternoon and will remain there throughout Sunday and until Monday morning.

The low is expected to move away to the east late on Monday allowing a ridge of high pressure to cross the state on Tuesday.

An initial flood watch is in place for the North, North East, North West, Huon, Derwent and South East with minor flooding likely from Saturday afternoon.

Isolated moderate flooding is possible at some locations in the northeast with the trough slowly moving into western Tasmania today as a cold front approaches the west.
